Specification of Letters Patent.

Application filed May 4, 1910. Serial No. 559,309.

1 citizen of the United States of Brazil, and

FERDINAND C. voN HEYDEBRAND, a citizen of the United States of America, both residing in Garfield, in the county of Bergen and State of New Jersey, have invented certain new and useful Improxements in Water and Air Proof Composition of Matter, of which the following is a specification.

This invention relates to an improved composition of matter which is to be used for rendering paper for cement and other bags, lining paper for barrels, coating of gastubes and fire-hose, engine-packing and other articles Water and airproof, and Whichcan also be used as a coating for damp floors, walls of cellars, structural iron, iron vessels, for rendering the same water-tight; and for this purpose the invention consists of an air and waterproof composition of matter made of a liquid mixture containing gutta-percha or caoutchouc, asphaltum, heavy hydro-carbons, such as tar, pitch, resin and earth-wax, filling material such as starch, dextrin,glycerin, and Chinawood or nut oil.

In prparing our composition of matter for rendering paper and other articles water and airproof, the following ingredients are mixed while boiling in the succession and proportions as follows:

oil.

, The tar, asphaltum, pitch and eartlvwax serve as a rubber substitute so as to reduce the expense of the composition and impart the required consistency to the same. The starch serves as a filler, the dextrin to impart the adhesive property, and the resin as a drier, while the glycerin keeps the compo-v sition flexible, and the China nut or wood oil in connection'with the caoutchouc or guttapercha imparts the waterproof quality to the composition, the substances impregnated with the same and to the objects treated,

coated or'painted with the same.

The ingredients are boiled together and intimately mixed with each other up to the proper consistencyas required for the diflerent uses, the proportions of resin being 'varied according as a more or less easilyflowing and drying mass is desired.

The paper or other articles are impregnated with an easily flowing liquid and then permitted to dry, while for gas-tubes, firehose and is required.

The proportions of the ingredients can be changed according to the object for which the composition is to be used. For some purposes a thin liquid, while for other purppses a liquid of a pasty consistency, and for still other purposesa thick liquid is required.

The composition after it is applied to the articles, dries quickly when applied in thin state, and more slowly when applied in thick state. The objects impre nated, saturated or coated with the liqui composition of matter are rendered perfectly water and airproof, the composition remaining flexible,

without becomingbrittle, which is due to the caoutchouc and glycerin employed, while the tar, asphaltum and pitch and the China nut oil impart the waterproof quality to the same and form to some extent a substitute for the more'expensive caoutchouc or guttapercha, so that a rubberlike property is imparted to the composition which has the advantage of being considerably cheaper than the rubber-compounds, and not liable to decomposition and deterioration as the same. Having thus described our invention, we

claim as new and desire to secure by Letters packing a layer of thicker liquid.
